Debunked

We all know math can be scary. In fact, I recently wrote about how intimidating all those numbers and figures can be.

But math is never more terrifying than when it crushes our deeply held beliefs and contradicts our political agendas.

For example, a recent study has shown that despite all the screaming and cries of calamity from the right wing, immigrants are not taking Americans’ jobs.

The study “found little to no negative effects on overall wages and employment of native-born workers in the longer term.” Basically, this means that when the GOP candidate for president slams immigrants — especially Latin American ones — he has no idea what he is talking about.

Of course, we all knew that already, but it’s nice to have hard data confirming that the guy is a lying shithead.

In any case, the report went on to state that immigration is “integral to the nation’s economic growth” because immigrants “bring new ideas and add to an American labor force that would be shrinking without them, helping ensure continued growth into the future.”

Specifically, high-skilled immigrants, especially in technology and science, have a significant “positive impact on Americans with skills, and also on working-class Americans. They spurred innovation, helping to create jobs.”

Furthermore, by flipping this argument on its head, we see that the GOP candidate’s plan to deport undocumented workers “would result in four million lost jobs by 2030.”

OK, so it’s settled that immigrants are not stealing jobs, and in fact, they may be kickstarting the economy to create new ones.

But what about that side claim that immigrants cost the US government bazillions of dollars each year in handouts and “free stuff”?

Well, the math is a little fuzzier on this one, and it may be true that recent immigrants cost more in government expenditures. However, any deficit is gone by the time the second generation (i.e., kids of immigrants) enters the work force, and “by the third generation, immigrant families contribute about $223 billion a year to government finances.”

The bottom line is that the net effect of immigration is positive, especially when one looks at the long term.

So I’ll ask again — don’t you just love math?

 


2+2= KKK

As a writer, I am supposed to despise math.

Look at it, looking all smug with its cosines and discontinuous divisors and irrational numerators.

It’s just so absolutely certain about the world. I must hate it.

But I don’t. Although I’ve always been drawn to words, I’ve never been intimidated by numbers. I did pretty well in math in school, although I never went past pre-calculus.

So I’ve never understood people who freak out about math, or panic at the mere sight of an equation. This fear, I believe, turns into a self-fulfilling prophecy, and soon people are insisting that they can’t do basic addition and throwing up their hands at polling data or stiffing the waiter because they don’t dare try to figure out the tip.

But maybe these mathphobes are on to something. Because to my great disappointment, it turns out that math is a big old bigot.

Yes, a recent book argues that “math is essentially being used for evil,” in that “algorithms and big data are targeting the poor, reinforcing racism and amplifying inequality.”

Now, inflammatory (and completely misleading) claims about math being “racist” aside, the point is clear. Numbers are only as good as the humans who input them. As such, “any algorithm can — and often does — simply reproduce the biases inherent in its creator, in the data it’s using, or in society at large.”

For example, “nearly half of U.S. employers ask potential hires for their credit report, equating a good credit score with responsibility or trustworthiness.” This is despite the fact that the reliability of these reports “has remained in doubt for more than a quarter century.”

But because of our faith in data — or our fear of numbers — we continue to think an equation is “superior to human judgment — never questioning the assumptions that get baked in.”

This is a flawed assumption, and it not only helps reinforce inequality, it taps directly into that most vile of human drives: racial prejudice.

It turns out that numbers are not as culturally neutral and objective as we would like. Again, this is not because the numeral “3” somehow dislikes Latinos or the figure “864” really hates blacks. It is because “while algorithms might work with data alone, it’s always human beings that decide what factors they weigh.”

So what can be done about this issue? To begin with, simple acknowledgement is necessary, combined with the awareness that one can prove just about anything with the right set of figures.

And then we can get the world’s mathematicians to work on creating a formula that will rid the world of bigotry. That will be one truly great equation, and it will, of course, most likely equal 42.


Hitting the Right Notes

I recently saw the movie Whiplash, which was a gripping look at the price of greatness. For those who haven’t seen the flick, it’s about a teenager jazz drummer obsessed with becoming a legendary artist.

Now, most of us are not willing to practice an instrument until our hands literally bleed, as the Whiplash protagonist does. But the good news is that you may not have to.

You see, a recent study showed that taking music lessons — just basic chord progressions, strumming skills and the like — greatly improves people’s language and reading skills.

Even more interesting is that the research was conducted on at-risk, low-income children, most of them Latino.

The researchers believe that the experience of making music creates a more efficient brain that helps a person learn and communicate better. But the study implies that at least two years of lessons are required before improvements kick in.

So what does this mean for Hispanic kids, who often live in disadvantaged areas? Well, it implies that investing in music education may help Latino children improve their learning skills and close the educational gap between Hispanics and other ethnic groups. The results also imply that for low-income students, music lessons can be as important as traditional classes in math and reading.

Because music is a key part of Latino culture, programs that offer music education will find a receptive audience in Hispanic kids. After all, I could not have been the only Latino kid who grew up on a steady diet of Santana and Julio Jaramillo. And that’s not even getting into all the salsa, rock, hip hop, and stray bits of classic country that finds its way into Latino homes.

Basically, we like to listen to a lot of music, so it should be a natural extension to get Hispanic kids to learn how to play it.

This research aligns with another recent study, which found that bilingual kids have more flexible brains and better cognitive abilities. Keep in mind that most of the demand for Spanish-language immersion schools is coming from white families who want their kids to master another language and gain exposure to diversity.

So it might not be long before you peek into a classroom and see a bunch of multiethnic kids speaking Spanish and jamming on blues standards.

Rock on.

 


Penny Arcade

Recently, I wrote about how Hispanics are underrepresented in the STEM fields. Well, this underrepresentation creeps up in strange ways.

For example, Hispanics are big on video games. We are 32% more likely to consider video games our main source of entertainment, and we are 54% more likely to buy a video game the day it’s released.

Personally, I used to be king of the arcade back in the days when Galaga ruled the Earth.

But for the most part, the video game industry has ignored their large Latino fan base. Just 3 percent of video game characters are Latino, and many of those are — to no one’s surprise — cliché or offensive stereotypes.

So what can be done about this? Well, big guns like Google have plugged in and are trying to get Hispanic kids excited about technology. And lots of organizations have sprung up to teach coding and programming to Latino children. And the Latino STEM Alliance partners with schools, industry groups and community leaders to bring enrichment programs to Latino kids.

While the goal is to create better job opportunities for Hispanics, an even more crucial objective is to accelerate the nation’s pace of scientific and technological innovation. You see, without the input of Latinos, that’s just not gonna happen.

As for me, I plan to encourage my toddler son to love science and technology. It’s not only smart for society and good for my boy, it’s my master plan for retirement. I figure in twenty years, my son will come up with the next Facebook, and the family will be set.

Hey, why not?

 


I Did Not Code This Website

Not to boast, but Latinos are the most tech-savvy demographic. We are more likely to be early adopters, own a smartphone, watch videos online, and engage in social media than other groups.

Basically, if there is an electronic gadget that flashes, whirrs, buzzes, whistles, or just lights up, we are there.

But as a recent report showed, we’re not so good at actually creating the gadgets in the first place. Diversity is a serious problem in Silicon Valley, and Latinos are underrepresented when it comes to developing new technology.

At the largest tech firms, Hispanic representation rarely cracks single digits, and it never comes close to being proportional to the Latino share of the population. Many tech industry leaders fear that innovation will suffer because so few ethnic minorities — including Latinos — are becoming programmers, engineers and entrepreneurs.

This means that in a nightmarish scenario to horrible to comprehend, developing Back to the Future-style hoverboards will never happen.

Why is this? It’s because we’re sucking at the stem. Or rather, we’re sucking at STEM (Science, Technology, Engineering, Math). You see, the number of STEM jobs significantly outpaces the number of people qualified for those jobs. Latinos account for about 17% of the U.S. population but only 7% of the nation’s STEM workers. Hispanics will make up more of the labor pool in the future, so you can see the problem. I mean, do the math…

Oh, wait. Maybe you can’t do the math, because you’re not into STEM. Damn, this is ironic… and awkward.

Well, you’ll just have to trust me.
